碩士 === 國立成功大學 === 電機工程研究所 === 84 === The current TV programs are almost in NTSC format. The resolution is not high enough because the number of scanning lines is only 525 and with interlaced mode. To improve the vision perception, the development of HDTV system is imperative. A HDTV system must include many features, such as high resolution, wide screen, high fidelity, and digital transmission. In order to compatible with the format of NTSC. The interpolation rocessing plays an important role during the conversion from the NTSC to HDTV system. However, if the processing images contain a lot of impulse noise, the interpolation will result in a blurring image. In this thesis, we focus on the processing of impulse of impulse noise of television images. To reach the real time a novel architecture which combing noise detection and noise filtering is proposed.
